Notes:
1. Selectable parameter specified by part number. See Section 3. "Ordering Information" on page 7 for further details.
2. OE and FS pins include a 17 kΩ pullup resistor to VDD. Pulling OE to ground causes outputs to tristate.
3. If the device is powered up below –20 ºC and the ambient temperature rises by approximately 105 ºC during normal
operation, the device will perform a one-time recalibration. The output is squelched for approximately 2–3 ms during
this recalibration.
